Training Voice Models

Building a Unit Selection Cluster Voice

(from here http://festvox.org/festvox/x3082.html)

  1. mkdir uw_uw_rdt
cd uw_uw_rdt
  1. uniphone setup:
     $FESTVOXDIR/src/unitsel/setup_clunits uw us rdt uniphone
  2. generate prompts and prompt files:
    festival -b festvox/build_clunits.scm '(build_prompts_waves "etc/uniphone.data")'
  3. record sound, using audacity. save as 16k, 16bit mono.
  4. make labels:
    ./bin/make_labs prompt-wav/*.wav
  5. build utterance structure:
    festival -b festvox/build_clunits.scm '(build_utts "etc/uniphone.data")'
  6. do pitch marking:
    ./bin/make_pm_wave etc/uniphone.data
  7. find Mel Frequency Cepstral Coefficients:
    ./bin/make_mcep etc/uniphone.data
  8. build cluster unit selection synth:
    festival -b festvox/build_clunits.scm '(build_clunits "etc/uniphone.data")'

Using a Unit Selection Cluster Voice Synth

  1. from uw_us_rdt directory:
    festival festvox/uw_us_rdt_clunits.scm
  2. in Scheme:
    (voice_uw_us_rdt_clunits) 
  3. (SayText "this is a little test.")

Building a CLUSTERGEN Statistical Parametric Synthesizer

adapted from http://festvox.org/festvox/c3170.html#AEN3172

  1. mkdir uw_us_rdt_arctic

uw_us_rdt_arctic $FESTVOXDIR/src/clustergen/setup_cg uw us rdt_arctic

  1. copy text into etc/txt.done.data. use some of the lines from here http://www.festvox.org/cmu_arctic/cmuarctic.data
  2. copy audio files into wav/
  3. use
    bin/get_wavs
    to copy files to power normalize and convert to proper format.

Building a Unit Selection Cluster Voice from TIMIT data

(from here http://festvox.org/festvox/x3082.html)

  1. mkdir uw_uw_rdt_timit
cd uw_uw_rdt_timit
  1. timit setup:
     $FESTVOXDIR/src/unitsel/setup_clunits uw us rdt timit
  2. generate prompts and prompt files:
    festival -b festvox/build_clunits.scm '(build_prompts_waves "etc/timit.data")'
  3. record sound, using audacity. save as 16k, 16bit mono.
  4. make labels:
    ./bin/make_labs prompt-wav/*.wav
  5. build utterance structure:
    festival -b festvox/build_clunits.scm '(build_utts "etc/timit.data")'
  6. do pitch marking:
    ./bin/make_pm_wave etc/timit.data
  7. find Mel Frequency Cepstral Coefficients:
    ./bin/make_mcep etc/timit.data
  8. build cluster unit selection synth:
    festival -b festvox/build_clunits.scm '(build_clunits "etc/timit.data")'


Improving Quality

Using Voices

using meghan voice

To run the server:

  • open terminal:

cd /Users/murmur/Desktop/meghan festival_server -c meghans_special_sauce.scm

  • To kill the server:

Control-C

  • To run the client:

open a 2nd terminal window: cd /Users/murmur/Desktop/meghan festival_client myfile.txt --ttw --output client_test.wav

  • Other stuff (python):

import os os.popen("/Applications/festival_2.1/festival/src/main/festival_client /Users/murmur/Desktop/meghan/myfile.txt --ttw --output /Users/murmur/Desktop/meghan/client_test78.wav")

Using new Voices

Modify new voice so festival knows it's there

  • append to uw_us_rdt_clunits.scm in uw_us_rdt_clunits/festvox:

(proclaim_voice

'uw_us_rdt_clunits
'((language english)
  (gender male)
  (dialect american)
  (description
   "This is Robert Twomey trained on CLUNITS, TIMIT databse.")))

(provide 'uw_us_rdt_clunits)

=Install voice to festival directory

  • http://roberttwomey.com/downloads/uw_us_rdt_clunits.tar.gz
  • unzip file from festival root directory, it should install to the correct directory
  • copy your newly trained voice to festival/lib/voices/english/
  • the name of your new voice directory (ex: uw_us_rdt_clunits/) needs to match the voice file (ex: uw_us_rdt_clunits/festvox/uw_us_rdt_clunits.scm)

Configure festival to use your voice by default

  • to set your voice as default, add the following to festival/etc/siteinit.scm:
(autoload voice_uw_us_rdt_clunits "/Users/rtwomey/code/tts/festival/lib/voices/english/uw_us_rdt_clunits/festvox/uw_us_rdt_clunits" "American English male uw_us_rdt_clunits")

(set! voice_default 'voice_uw_us_rdt_clunits)

(voice_uw_us_rdt_clunits)
(lex.add.entry '("<break>" n (((pau pau) 0))))
